Clemens Ladisch 9d60ef2bd8 firewire: ohci: lazy bus time initialization
The Bus_Time CSR is virtually never used, so we can avoid burning CPU in
interrupt context for 1 or 3 IsochronousCycleTimer accesses every minute
by not tracking the bus time until the CSR is actually accessed for the
first time.
